ものである。[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a rapid preheating system for starting a diesel engine in cold conditions, and particularly to a rapid preheating system for diesel engines that shortens the starting time and provides stability after starting. It's about a solid system.

等に効果があった。Conventionally, diesel engines have had poor starting performance, especially in cold weather, and have had to be started using some kind of assistance. Typical examples include glow plugs and intake heaters (electric heating type,
There are several types (combustion type), but each has its own advantages and disadvantages, making them difficult for drivers to use. For example, glow plugs are located inside the smoking chamber, so they can easily explode completely, but they do not have enough heat capacity, and after startup, there are problems such as poor blow-up due to lack of warm air, and white smoke that does not disappear. On the other hand, the intake heater does not preheat the air in the combustion chamber, making it difficult to start, but once it has completely exploded, a relatively large installed heater can send in warmed intake air, preventing blow-up and white smoke. was effective.

る。Traditionally, diesel engines equipped with glow plugs have good starting performance but poor stability after starting, while diesel engines equipped with intake heaters have poor starting performance but good stability after starting, which are contradictory characteristics. It was thought that they had it. But this? On the contrary, if we combine only the advantages of both, we can obtain an ideal preheating system with good startability and stability after starting. On the other hand, as there is a high need to shorten the preheating time of diesel engines, control systems that perform rapid preheating by applying overvoltage and then stably heat the engine by connecting a drop resistor in series are becoming popular. So, what about the intake heater and glow plug in this system? If you incorporate it, that is, use a glow plug as a rapid preheating source and an intake heater as a drop resistance, the combustion chamber will be rapidly preheated due to the good start-up of the #Vi glow plug, and once it is fully detonated, the glow plug and intake heater will be activated. An extremely large amount of heat? By introducing it into the intake air, it is possible to improve stability after startup, blow-up force performance, etc.

に示す。FIG. 1 shows an embodiment of the present invention. First, by turning on the key switch 2k, the control unit 7 turns on the relays 3 and 4, and the voltage of the battery 1 is applied only to the glow plug 5, which starts the combustion.・Rapidly preheat the Akatsuki room. Next, when the key switch is turned to the 2kST position, relay 4 is turned OFF, and the intake heater 6 and glow plug 5 are opened in series, allowing stable preheating. At the same time, it reduces the current and makes cranking easier. Next, when the engine starts and the key switch 2a is returned to the ON position, preheating changes to after-heating.The intake air is warmed up by the glow plug 5 and the intake heater 6 for a certain period of time, and then the relay 3 is also turned OFF, and the system operates. ends. Note that the glow plug 5 in this system has a rating lower than the battery voltage (70 to 8
0% rating), and this is used for rapid preheating, but if it is connected in series with the intake heater 6, it will be used at almost the rated value. The above energization time chart is shown in FIG.
